Excerpt from The Technical World Magazine, Vol. 5: July, 1906 The inclination of the equator of Mars to its orbit is or about the same as that of the Earth. The seasons on the two planets are therefore identical, except that, on account of the longer year, those on Mars are twice as long as our own. The Martian day is about forty minutes longer than ours. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
